b b b b
and Genomes
b b
Key bConcepts
• Inherited b traits bare b affected bby bgenes.
• Genes b are b composed b of b the b chemical b deoxyribonucleic b acid b (DNA).
• DNA breplicates b to b form b (usually b identical) b copies b of b itself.
• DNA bcontains ba bcode bspecifying bwhat btypes bof benzymes band bother bproteins
bare bmade bin bcells.
• DNA boccasionally bmutates, b and bthe bmutant bforms bspecify baltered bproteins.
• A bmutant benzyme bis ban b"inborn berror bof bmetabolism" bthat bblocks bone bstep
bin ba bbio- bchemical bpathway bfor bthe bmetabolism bof bsmall bmolecules.
• Traits bare baffected bby b environment bas bwell bas bby bgenes.
• Organisms bchange bgenetically bthrough bgenerations bin bthe bprocess bof
bbiological bevolution.
• Because bof btheir bcomm.on bdescent, borganisms bshare bmany bfeatures bof btheir bgenetics
and bbiochemistry.
Key bTerms
1. complementary bbase bpairing
2. antiparallel
3. central bdogma
4. transcri b tion
5. ribosome
6. transfer b RNA b (tRNA)
7. proteome
8. substrate
9. alkaptonuria
10. phenylketonuria
11. pleiotropic beffect bor bpleiotropy
12. prokaryote
Concepts bin b Action
1.1. (a) bfalse; b(b) btrue; b(c) btrue; b(d) bfalse.
1.2. The bimportance bof bthe bnucleus bin binheritance bwas bimplied bby bits
bprominence bin bfer- btilization. bThe bdiscovery bof bchromosomes binside bthe
bnucleus, btheir bbehavior bduring bcell bdivision, band bthe bobservation bthat beach
bspecies bhas ba bcharacteristic bchromosome bnumber bmade bit blikely bthat
bchromosomes bwere bthe bcarriers bof bthe bgenes. bMicro- bscopic b studies
b showed b that b DNA b and b proteins b are b both b present b in b chromosomes, bbut
bwhereas bnearly ball bcells bof ba bgiven bspecies bcontain ba b constant bamount bof
bDNA, bthe bamount band bkinds b of bproteins bdiffer bgreatly bin bdifferent bcell
btypes.
